.jApplication filed May l, 1896. Serial No. 592,389. (No model.)

T0 a/ZZ whom it 71am/ concern:

Be it known that I, CHARLES F. HOOD, a citizen of the United States, residing at Pittsburg, in the county of` Allegheny and State of Pennsylvania, have invented or discovered a certain new and useful Improvement in Processes of and Apparatus for Cleaning Waste,

dac., of which improvement the following lis a specification. I

The invention described herein relates to certain improvements in removing oil or greaseaanddirt from Waste or other solid materia-land in saving the oil which is removed from the waste. It has heretofore been customary to employ benzin for this purpose, the

waste being soaked inthe benzin and then washedg' This process,whileeifective to clean the waste, is expensive on account of the apparatusand labor employed not only in cleaning the waste, but also `in saving the oil and benzin. 'd Y The object of the present invention is to provide for the easy and quickfand efficient removal of the oil from the waste and the subsequent separation of the oil without ,any material loss of either the waste or oil. j

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure l is a view, partly in elevation and partly in section, of my improved apparatus; and Fig. 2 is a top plan view of the same.

Inthe practice of my invention it is preferred to employ a long tank l, which is divided into two or more receptacles, which, for convenience, will be termed vats, by double transverse walls or partitions 2, which are of less height than the main walls of the tank and are arranged a short distance apart to form receptacles 3 for overflow from the vats. In the bottom of each vat is placed a distributer or jet device consisting of a frame 4, preferably formed of metal, and of diaphragms 5, formed of perforated metal and secured to the edges of the frame 4. 1 On top of the distributer is placed a frame 6, formed of wood or other suitable material and having its upper end covered with wire-netting 7. On top of the frame 6 is placed a second similar frame 8, andjonzthis is placed a second diaphragm A9, of Wiremetting. These diaphragms 7 and 9 are preferably strengthened by a stiff wire at their edges.

Pipes 10, connected to a suitable steam-gen- 5 5 erator, are passed through the walls of the tank andare connected to the distributer, and pipes ll, for introducing hot water in the vats, are passed through the walls of the tank, but are not necessarily connected to the distribu- 6o ter.

The waste to be cleaned is placed loosely upon the diaphragm or wire-netting 7, within the frame S, and then the diaphragm 9 is placed' on the frame 8 and secured in position 65 by turn-buttons l2 or other suitable lock. Hot waterf is then admitted until the vatis lled to or a little below the diaphragm-7. Steam under considerable pressure is next permittedto flow into the distributer, and 7o passes through the diaphragms 5 and 7, and the waste nally escaping through the diaphragm 9 the steam expands in thedistributer, and by reason of the perforations in the upper diaphragm 5 the steam is separated into 75 I a large number of small jets, in which form it passes up through the waste. In passing through the water in and above the distributer the steam becomes thoroughly saturated, and by reason of the velocity of the steam- 8o jets a considerable quantity of water is carried up thereby in theform of small jets in addition 'to that contained iny the saturatedA steam. Y

The action of the hot steam andV water permeating the whole mass of waste loosens the oil, &c. and the mechanical action 'of the quick-movin g jets of steam and water removes the oil, dac., from thewaste and forces them above the diaphragm, where they are held by 9o the action of the jets. It is characteristic of my improved method of cleaning that the waste is held while being cleaned entirely above the water contained in the vat, as, if surrounded or partially immersed in water, the latter would deaden the velocity of the jets and thereby lessen the effective mechanical action of the jets on the waste. After theioil, &c.,

have been removed from the waste and forced above the diaphragm Water is admitted, so as roo to iill the vats and flow over the partitions 2 into the receptacles 3. Dnrin g this admission of the hot Water for the purpose of removing the oil, dac., the iioW of steam is continued at least until the Water has risen sufficiently high to lift the oil and scum from the diaphragm 9, so as to prevent the oil and scum from settling back upon the Waste. It is preferred to continue the flow of steam until all the oily scum floated up by the Water has y passed into the receptacles 3,'as the steam will agitate the Water, thereby imparting a rinsing action. After the scum has been removed in the manner stated the valves in the steam and Water supply pipes are closed and the valve in the escape-pipe 13 opened to allow the Water in the vat to flow out, so as t permit of the removal of the cleaned Waste and the placing of another quantity to be cleaned in position, as stated. The receptacles 3 are provided with suitable escape-pipes 14 for conducting the mixed Water and oil to a suitable tank where they can be separated.

Itis characteristic of my improvement that, While the Waste is thoroughly cleansed, there is not any loss or tangling of the fiber of the Waste, as it is so held that as a body it will not be beaten about by the steam-jets, and also all the oil contained in the Waste is saved and can be utilized in the arts.

I claim herein as my inventionl. As an improvement in the art of cleaning Waste, the method herein described, which consists in confining the Waste in a receptacle having perforated Walls above a Water and steam supply, and then simultaneously forcing jets of steam and Water through the confined Waste in such manner vas to force the dirt and oil out of and to one side of the material to be cleansed, substantially as set forth.

2. As an improvement in the art of cleaning Waste, the method herein described, which consists in confining the Waste in a receptacle having perforated Walls and above a basin of Water, forcing jets of steam and Water into the confined Waste, and then, by a further supply of Water, floating off the oily scum removed by the action of the jets, substantially as set forth.

3. In an apparatus for cleaning Waste, the combination of a vat, a steam-distributer arranged in the vat, a receptacle for confining the Waste provided With perforated bottom and top and supported a suitable distance above the distributer, a steam-supply pipe connected to the distributer, and a Watersupply pipe connected to the vat, substantially as set forth.

In testimony whereof my hand.

I have hereunto set CHARLES F. HOOD.
